About the Bower SDF 680

The Bower SFD680C Digital Shoe Mount Flash is an economical flash, with TTL flash support for digital SLR cameras. This version is dedicated to the Canon digital SLR camera line and fully supports Canon's E-TTL II flash operating system.

The flash features an auto-zoom flash head, which auto-senses the focal length of the camera's lens and adjusts itself accordingly, within the range of 28mm to 85mm. It can also tilt and swivel for complete creative control. Its light output can be adjusted with a range of +/-1 EV in 0.5 increments (5 settings). It is an ideal economical all-around flash for any digital or 35mm autofocus SLR shooter.
